Friends - I have a new-ish PS Audio Signature preamp and 250 amp. In both of their user manuals the manufacturer suggests that the stock fuses be replaced "but we
recommend care be taken to use H-Rated fuses, specifically tailored for high current, high transient
in-rush conditions." My preference is to use Synergistic Research blue fuses. There are 250 and 500 slow-blow and fast-blow options of difference sizes. My question is, are they all H-rated? I can't find anything in Synergistic's online literature, so I'll ask you all.
Something For The Fuse Guys ...
There are fuses, and then, there are fuses.
I'm evaluating some prototype fuses that I received in the mail three days ago.
Over the past few years, I've used fuses from five different manufacturers. The last three were the Red, Black and Blue fuses from Synergistic Research. Each one incrementally improved the sound of my system. My favorite so far was the SR Blue.
The prototype fuses being evaluated presently raises the SQ beyond all of the others mentioned above. The major improvement to my ears is better tonal accuracy. Instruments and voices are more life-like. The noise is reduced allowing for a more solid 3-D presentation with the musicians more solidly presented on the sound stage. Overall, more information is fleshed out of CDs and LPs.
The manufacturer, the price and the name of the prototype fuses will come later. I don't have the information thus far. My understanding is, if all works out, the release date is to be mid-October.
Stay tuned ...

@ jimkiely- Personally; I’ve found the tech people and owners at PS Audio very accessible. You might ask them if they’ve any experience/concerns, with the Synergistic fuses. https://www.psaudio.com/contact/ |
I have had mixed results with audiophile fuses. My rectifier tube in my power supply went bad and blew out the fuse in my power supply. That was an expensive blow. I replaced the fuse in my preamp with a blue fuse of the same amperage, it blew. It was within the warranty period so I had a one step increase in the amperage rating. They upgraded me to an orange fuse and so far so good. |
